TROUBLESHOOTING
The instructions shown on the display of the Emitter and the Receiver enable the user to identify the
cause of a number of system malfunctions. As described in the “SIGNALS” paragraph of this manual,
in case of a failure, the system is set to the stop condition and the display of each unit shows the letter
F followed by a numerical code that identifies the type of failure. (See table below).
EMITTER
CODE
DISPLAYED
DIAGNOSIS
REMEDY
Anomalous connection of SEL
RANGE/TEST signals
Check the connection of terminals 2 and 4 (SEL RANGE/TEST) on
the connector carefully.
Internal failure relating to the
add-on boards
Return the equipment to ReeR laboratories for repair.
Internal failure relating to the
microcontroller boards
Internal failure
RECEIVER
CODE
DISPLAYED
DIAGNOSIS
REMEDY
Overcurrent on one or both
outputs (OSSD)
Check the connection of terminals 2 and 4 (OSSD) on the connector
carefully. If necessary, reduce the load by reducing the requested
current to max. 500mA (2.2 F).
Detection of a hazardous
interfering Emitter condition. The
Receiver is able to receive the
beams emitted by two different
Emitters at the same time.
(This fault is displayed for at
least 30 seconds).
Locate the Emitter that is the cause of the disturbance and proceed
as follows:
reduce the range of the interfering Emitter from High to Low
(see table 2)
Invert the positions of the Emitter and Receiver
Move the interfering Emitter to prevent this from illuminating the
Receiver
Use opaque guards to shield the beams coming from the
interfering Emitter
Connection of load between
static outputs (OSSD) and the
positive power supply line (+ 24
Vdc)
Check the connection of terminals 2 and 4 (OSSD) on the connector
carefully. Caution: the load must be positioned between the outputs
(OSSD) and 0 Vdc.
Internal failure relating to the
microcontroller boards
Return the equipment to ReeR laboratories for repair.
Erroneous connection of static
outputs (OSSD).
Check the connection of terminals 2 and 4 (OSSD) on the connector
carefully. These terminals can be connected directly to + 24 Vdc or
to 0 Vdc.
